U of Toronto study finds US electrification of LDV fleet not a silver bullet for tackling climate change in vehicle sector

Green Car Congress

A new study by researchers at the University of Toronto has found that current US policies are insufficient to remain within a sectoral CO 2 emission budget for light-duty vehicles that is consistent with preventing more than 2?°C The paper is published in the journal Nature Climate Change.

New method details contributions of climate change & natural variability to rapid Arctic ice loss

Green Car Congress

A new study finds that a substantial chunk of summer sea ice loss in recent decades was due to natural variability in the atmosphere over the Arctic Ocean. The study, from the University of Washington, the University of California Santa Barbara and federal scientists, is published in Nature Climate Change.

How Engineers Can Help Protect Earth From Worsening Climate Change

Cars That Think

Fortunately, we still have a narrow window of opportunity to alter the Earth’s climate path, and I believe we can do it. Climate change is a global societal crisis that is causing devastating consequences. Deforestation is contributing to climate change. We need to address the crisis now in a sustainable way.

Study finds Colorado River Basin’s worst known megadrought was 1,800 years ago

Green Car Congress

An even more intense “megadrought” hit the region around 1,800 years ago, according to a new study published in the AGU journal Geophysical Research Letters. The new study used tree-ring data and other climate records to identify a drought period unmatched in severity by the current drought or other ancient droughts.

Study finds 12-30% fuel consumption gap between certified and real-world use in China

Green Car Congress

A team from the Innovation Center for Energy and Transportation (iCET) reports that while average certified fuel consumption (FC) decreased by 15% between 2008 and 2017, real-world FC remained unchanged, resulting in a fuel consumption gap increase from 12% to 30%. The paper is published in the journal Energy Policy. —Dror et al.

Studies find global COVID-19 lockdowns have significantly reduced PM2.5 and NO2 pollution, but ozone up

Green Car Congress

Two new studies in AGU’s journal Geophysical Research Letters find nitrogen dioxide pollution over northern China, Western Europe and the US decreased by as much as 60% in early 2020 as compared to the same time last year. In addition to nitrogen dioxide, one of the new studies finds PM 2.5 Grey areas indicate no valid data.

Study finds megacity traffic soot can reach high altitudes and be transported over long distances, contributing to global warming

Green Car Congress

A reduction of soot particles through driving restrictions for old diesel vehicles can therefore significantly reduce the health impact, as studies by LfULG and TROPOS have shown based on the low emission zone in Leipzig 2017. Soot is also slowing down efforts to limit climate change by reducing greenhouse gas emissions.
